Math Help - [SOLVED] Graphing a parabola, finding focus/directrix/vertex

1. [SOLVED] Graphing a parabola, finding focus/directrix/vertex

Well I've completed pretty much every other problem so far except this one, it stumps me. I believe I must complete the square but I've forgotten how I must go about doing that. I tried it already and nothing worked out and it didn't factor correctly to the answer.

$y=1/4(x^2-2x+5)$
